BREECH-LOADING GUN.

SPECIFICATION forming part of Letters Patent No. 341,751, dated May 11,1886.

Application filed March 15, 1886.

.To all whom it may concern.-

Be it known that I, Dinnnnion W. JANSEN, a citizen of the United States,and a resident of Joplin, in the county of Jasper and State of Missouri,have invented certain new and useful Improvements in HammerlessBreech-Loading Guns; and I do hereby declare that the following is afull, clear, and exact description of the invention, which will enableothers skilled in the art to which it appertains to make and use thesaine, reference being had to the accompanying drawings, which form apart of this speciiication, and in which- Figure 1 is a perspective viewof my improved breech-loading hammerless gun. Fig. 2 is a view of theupper side of the gun. Fig. 3 is a view of the under side of the gun.Fig. 4 is a view of the upper side of the gun, showing the lock-casingopened. Fig. 5 is a longitudinal vertical sectional View of the gun.Fig. 6 is aperspective detail view of the trigger-plate and the triggersremoved from the gun.

Fig. 8 is a view of the gun with the barrels removedand the lock and barrel seat removed and shown above the stock, and Fig.9 is a perspective detail View of the guard and its bolt with theeccentric disk.

Similar letters of reference indicate corresponding parts in all thefigures.

This invention relates to breechloading guns in which the hammers areconcealed; and it consists in the improved construction and combinationof parts, as will be hereinafter more fully described, and pointed outin the claims.

In the accompanying drawings, the letter A indicates the stock, whichmay be of any suitable construction, and which is formed with a recess,B, in its upper side for the reception of the lock and barrel seat D.The rear end of this seat is provided with a block, Gr, the rear face ofwhich is formed with a heavy upwardly-pointing hook, E, which engages arecess, F, shaped for its reception in a block, G, having arearwardly-projecting curved tongue, H, which is secured to the upperside of the stock by means of a screw, I.

The barrels J J are connected in the usual manner, and are provided neartheir breech Serial No. 195,190. (No model.)

ends with a downwardly-proj ecting perforated tongue, K, which issecured in the recess Lin the stock by means of a pin, M, passingthrough the stock and through the recess and perforation of the tongue.rlhe breech ends of the barrels rest upon the forward end of the seat,which is thus held in place by them atits forward end, while the rearend is held in place by the hook at its rear end. The side of one of thebarrels is provided with a long cylindrical eye, N, through which passesa long pintle, O, the forward end of which is provided with a head, P,which bears against the forward end of the eye, and the rear end of thepintle is inserted through an eye, Q, projecting from the side of theblock at the rear end of the lock and barrel seat, where it is providedwith a nut, R, which bears against the rear end of this eye.

A tube, S, is secured to the side of one of the lock-casings, T, whichare shaped similarly to the barrels,and fill the space between thebreech ends of the barrels and the block at the rear end of the seat,and this tube turns' wardly-projecting outer end, W, of an arm,

X, projects into this slot. The arm slides below the forward end of thelock-seat, and has the lower end of a pin, Y, secured to its inner end,which pin slides in a longitudinal slot, Z, in the forward end of thelock-seat.

The portion A which connects the barrels is formed with a groove, B', inits under side, corresponding to the longitudinal slot, and a bar, C',slides in this groove and has a cartridge-extracting lip, D', projectingupward from its rear end, portions of the said lip projecting into thebreech ends of the barrels and forming portions of the cartridge-seatsat the said ends of the barrels. rllhe twist of the slot in the tube ofthe lock-casings is such that when the lock-casings rest in their seatthe pin in the slot and the extractor will be in its forward position,the lip of the extractor resting in its notches in the breech ends ofthe barrels, and when the lock-casings are swung out to the side the pinwill be forced rear- ICO Q @4197er ward, drawing the arm and extractorrearward with it, throwing out the empty shells from the breech ends ofthe barrels.

The outer lock-casing, or the casing which is not hinged, is providedwith a laterallyprojecting lip, E,which projects out th rough a notch inthe edge of the lock-seat, and the said easing is also provided withasmall notch or recess, F', to the rear of the lip, into which notch theinwardly-projecting stud G upon the free end of a fiat spring, H',secured to the block of the lock-seat, may project, holdingthelock-casings in place when they are turned down in their seat, andallowing them to be tilted out to the side when the lip upon them isengaged.

The lock-casings are tubular, and havelongitudinal slots I in theirunder sides, extending from the rear ends to slightly past their 2Omiddles, and screw-threaded caps J t in the forward screw-threaded endsof the casings, and are formed with central perforations, K, therearends of which expand. Coiled sprin gs L fit with their forward endsupon the rear reduced and screwthreaded portions, M', of the screw-caps,and the rear ends of these spl'ings lit upon the forward reduced andscrew-threaded ends, N of two blocks, O', which fit and slide within thelockcasings.

These blocks are formed with axial perforations P', in which slide thesmooth inner portions of two screws, Q', which are provided with smallcoiled springs R', wrapped around them and placed between their headsand the rear ends of the blocks, while the forward screw-threaded endsof the said screws fit into axial screw-threaded perforations S in therear ends of the firing-pins T. The reduced forward ends tit into andmay project slightly 40 through the perforations of the screw-caps. Pinsor sears U project from the sliding harn mer-blocks through the slots inthe lock-cas ings, sliding in the same.

The rear end ofthe bottom of the lock-seat is formed with twolongitudinal slots, VV, which register with the slots in thelock-casings, and the forward ends of these slots are formed withenlargements XV toward the free side of the lock-casings, allowing thesears to enter the slots when the casings are tilted into the lockseat.

The trigger-plate X is secured to the under side of the gun stock, andis formed with an upwardly-projccting post, Y', through the upper end ofwhich passes a pin, Z', having its ends projecting at both sides of thepost. The upper ends of the triggers A are pivoted ppon the ends of thispin and project forward,while the rear or lower portions, B, of

6o the triggers are bent at right angles, or nearly so, to the upperportions and project downward through longitudinal slots C in thetrigger-plate, one trigger projecting down slightly behind the other, sothat each trigger may be drawn without disturbing' the other.

rlhe forward ends of the triggers are formed with upwardly-projectinglips D", beveled at their forward faces, so that the lower beveled endsof the sears may be drawn over the said lips and thereupon be engaged bythe same, the forward ends of the triggers having springs E forward oftheir fulcra, which springs force the lips of the triggers upward.

A shaft, F", is journaled with its upper end, which is provided with anut, G, in the lockseat at the forward ends of the longitudinal slotsbetween the same, the nut bearing against the upper side of the saidseat, and immediately below the under side of the seat this shaft isprovided with a round disk, H seO cured to the shaft by a lip, l,projecting from its periphery, and this disk or arm is capable of beingturned with the shaft to both sides toward the beveled lips of thetriggers. The lower end of the shaft projects through the forward endofthe trigger-plate, being journalcd in the same, and the forward end ofthe trigger-guard J is secured by means of a nut, K", to the said lowerend. The rear upwardly and forwardly curved end, L, of the said guard isformed with apcrforation, M, which may fit over around stud, N,projecting from the rear end of the triggenplate, so as to hold theguard in its position, the springiness of the metal in the guard forcingthe perforation upon the stud and allowing it to slip off from the studwhen the guard is drawn 4to either side.

It will now be seen that when the guard is turned to one side, andthereupon to the other side, the disk or round arm, which projectsforward when the guard is in its normal position, will be forced againstthe ends of the sears, which project down through the slots in thelock-casings and in the lock-seat, and the sears will be forced backsufficiently against the springs of the hammer-blocks to engage the lipsof the triggers, which will hold them back cocked. W'hen now thetriggers are pulled, lthe sears and hammer-blocks will be drawn forwardby the springs, and the impetus given to the blocks land the firingpinsby these springs will cause the firing-pins to ily out through theperforations inthe screwcaps, striking the fulminate orcap of thecartridges, which have been inserted into the barrels, and firing them,whereupon the small spiral springs between the heads of the screws inthe rear ends of the liring-pins will draw the said screws back, and thefiring-pins with them, drawing the forward ends of the firing-pins intothe perforations of the screwcaps, so that the lock-casings may betilted out by the lip upon them turning with the tube upon thehinge-pintle. This opening of the breech end of the barrels by turningthe lock-casings will cause the cartridge-extractor to be forcedrearward, drawing the empty shells with it, and the gun may be reloadedand the firing-pins and blocks cooked by means of the guard and theround disk or arm after the lock-casings have been closed down into theseat.

It follows that the barrels may be rifled or smooth, as may be desired,and that the mechanism may as well be'employed to a singlebarreledfire-arm as to a double-barreled firearm as long as the principleremains the same, and various changes may be made in the construction ofthe several parts, as well as por` tions of the mechanism may be used inconnectionwith portions of other similar mechanisms without departingfrom the spirit of my invention.

The triggers and the sliding ham nier-blocks, with theirdownwardly-projecting sears, may be used with different means forforcing the blocks back, and hammer-blocks with downwardly-projectingsears may be used with different firing-pins, and all such changes maybemade in the construction of the mechanism without departing from thegeneral principles of the mechanism.

The coiled spring at the rear end of the tube, which projects from thelock-casings and is hinged upon the pintle, serves to allow thelock-casings to be moved slightly rearward while being closed, for thepurpose of yielding to any slight obstruction which might be met withfrom the inserted shells in the breeclles of the barrels, or to enablethe lock-casings to yield if the cartridge extractor should meet withresistance in withdrawing the cartridgeshells.
